Mobile DevTools

About this app

Mobile DevTools brings a Chrome-DevTools-style Network inspector to Android. Watch every network request your apps make - in real time, on your own device, with no root and no PC required.

It works by running a local VPN on your device to capture outbound traffic, then presenting it in a clean, developer-focused interface built for debugging, QA, and security testing of your own apps.

━━━ WHAT YOU CAN DO ━━━

• LIVE NETWORK MONITOR - A real-time list of requests as they happen, with the originating app's icon and name, method, host, path, status code, duration and size. Smooth even with thousands of entries.

• PER-APP ATTRIBUTION - Every request is tagged with the app that made it. See at a glance who is talking to the network.

• REQUEST DETAILS - Full breakdown: URL, method, scheme, protocol, remote IP, timing, and request/response headers.

• BEAUTIFUL JSON VIEWER - Inspect JSON bodies with syntax highlighting, expand/collapse, and one-tap copy of any value or the whole document.

• POWERFUL SEARCH & FILTERS - Filter by method or status, and search across URL, domain, headers, and (optionally) request/response bodies.

• STATISTICS - At-a-glance charts: status-code distribution, request methods, data usage, top applications and top domains.

• APP INSPECTOR - Drill into any app to see its request count, total traffic, busiest domains, and full request history.

• HTTPS INSPECTION (optional) - Install the built-in certificate authority to decrypt HTTPS and view headers and bodies for apps that trust it. Certificate-pinned apps remain metadata-only.

• EXPORT - Share captured traffic as JSON, HAR (imports into Chrome DevTools and other tools), or plain text.

• POLISHED UX - Material 3 design, light/dark/system themes, and a fast, modern Jetpack Compose interface.

━━━ PRIVACY FIRST ━━━

Everything happens on your device. Captured traffic is stored locally and is NEVER uploaded, shared, or sent anywhere. There are no ads, no analytics, and no accounts. You control your data: cap how much history is kept and clear it any time. The VPN is used purely to capture traffic locally - it is not a proxy or anonymizer and routes nothing through external servers.

━━━ IMPORTANT ━━━

This is a developer/QA/security tool intended for inspecting traffic on your own device. HTTPS decryption only works for apps that trust a user-installed certificate; on Android many apps (and any using certificate pinning) will show connection metadata only. IPv6 flows are not captured in this version.

━━━ WHO IT'S FOR ━━━

Mobile developers debugging API calls, QA engineers verifying network behavior, and security researchers auditing their own apps.

What’s new

What's new in 0.2.0

• HTTPS decryption now captures full request and response bodies (gzip/deflate decoded) in a syntax-highlighted JSON viewer.
• Decrypted requests now appear instantly on keep-alive connections — no more missing calls.
• Updated CA setup for Android 11+: export the certificate, then install it from Settings. Added a shortcut to remove it.
• HTTP/3 (QUIC) is blocked while decrypting so HTTPS traffic stays inspectable.
• Reliability and stability fixes.
